Fig. (7) Live/dead viability test of HLE-B3 lens epithelial cells incubated with Mibefradil-containing micro particles after 24 h. Almost all cells of the control as well as of the Mibefradil concentration 10 µM seem to be alive (green), whereas incubation with 20 and 30 µM Mibefradil resulted in cell dead in these subconfluent growing cells (red).
